Four chromosomal races (2n=36, 3n=54, 6n=108, 8n=144) and 96 clones have been revealed among 224 specimens of the earthworm Aporrectodea rosea over the territory of Ukraine by means of karyological analysis and biochemical genetic marking. Each population has been showed by several clones at least; moreover the clones from different places have never been identical. The clones in the range of o...

vermicompost produced from sugarcane bagasse (sbv) or sawdust (s) were substituted at a range of different concentration in soilless bedding plant container medium, as a peat: vermiculite: perlite (6:3:1), to evaluate their effects on the growth of dieffenbachia amoena in the greenhouse. dieffenbachia amoena was grown in container medium pe: ve: p (6:3:1), in that peat substituted with 0%, 10%,...

Study is on the performance of earthworm species in vermicomposting salvinia was reported earlier. In this study reactors inoculated with single and combination two or three reported. The experiment carried out seven set vermireactors, i.e. mono - Eudrilus eugeniae, Eisenia fetida, Perionyx excavatus., di eugeniae +Eisenia fetida., fetida + excavatus multi excavatus. multi–species reactor achie...

Earthworms possess antioxidant, antibacterial, antitumor, and hemolytic properties. To recognize the molecules responsible for various biological activities of earthworm’s coelomic fluid, a detailed knowledge about its protein contents is required. The aim of this study was to characterize the proteins present within the coelomic fluid of Eisenia foetida earthworm. Polyacrylamide-gel-elec...

—In the last decade the invasion of European earthworms into previously wormfree glaciated areas of North America has stimulated research into their impacts on native forest ecosystems in the region. As a first approximation, the impacts of invading earthworms are related to their biomass. However, direct measurements of biomass can be significantly affected by the moisture conditions under whi...

Hermaphroditic lumbricid Eisenia sp. earthworms are ubiquitous and highly resistant to a variety of environmental stressors, including heavy metals. Among the progeny laboratory mated inter-specific pairs fetida (Ea) andrei (Ef) there fertile Ha hybrids derived from Ea ova fertilized by Ef spermatozoa very rare sterile Hf spermatozoa. The aim first part experiment was compare life traits whole ...

The morphological and anatomical simplicity of soil dwelling animals, such as earthworms, has limited the establishment of a robust taxonomy making it sometimes subjective to authors' criteria. Within this context, integrative approaches including molecular information are becoming more popular to solve the phylogenetic positioning of conflictive taxa. Here we present the description of a new l...

Survival of earthworms in the environment depends on their ability to recognize and eliminate potential pathogens. This work is aimed to compare the innate defense mechanisms of two closely related earthworm species, Eisenia andrei and Eisenia fetida, that inhabit substantially different ecological niches. While E. andrei lives in a compost and manure, E. fetida can be found in the litter layer...
